Buescher, a NASCAR XFINITY Series regular, is scheduled to make his third career Sprint Cup Series start for the Bob Jenkins-owned team in Saturday night's Duck Commander 500. He'll be pulling double-duty, driving the Roush Fenway Racing No. 60 Ford in Friday's O'Reilly Auto Parts 300 for XFINITY cars.

Buescher is the fourth driver in six races for the No. 34 team. David Ragan began the year, but hopped in as the interim driver for the injured Kyle Busch in the Joe Gibbs Racing No. 18 Toyota. That move set off a chain of driver swaps, putting Joe Nemechek behind the wheel at Atlanta in the season's second race.

Michael Waltrip Racing development driver Brett Moffitt competed in the next two events (Las Vegas, Phoenix) for Front Row, but rejoined MWR in its No. 55 Toyota after Brian Vickers was ruled out indefinitely with a recurrence of blood clots. That move made Buescher an 11th-hour replacement at Auto Club Speedway and the interim driver at Martinsville Speedway.

Ragan is expected to resume driver duties for the No. 34 team once Busch returns from injury.

Buescher notched his only XFINITY Series victory last August at Mid-Ohio Sports Car Course. He currently ranks second in the XFINITY standings, just five points behind series leader Ty Dillon after five of 33 races scheduled this season.
